Frequently Asked Questions

• Can it run a 1‑phase motor?
  No, it requires a 3‑phase induction or PM motor.
• Is the keypad included?
  No, it is sold separately. Check accessories.
• What is the maximum cable length?
  Up to 50 m shielded motor cable recommended.
• How to reset a fault?
  Press the reset button or cycle power.
• Does it support external braking resistor?
  Yes, terminals are provided for dynamic braking.
• Can I use it at high altitude?
  Up to 1000 m; derate above 1000 m.

Experience‑based Q&A

• Why does my motor vibrate at low speed?
  Enable auto‑tune and set correct motor parameters.
• How to avoid nuisance trips?
  Increase acceleration time and check input voltage.
• Which fieldbus is most stable?
  Modbus RTU works reliably for most users.
• Can I copy parameters to another drive?
  Use the copy function via keypad or software.

Selection Guide

• Match motor HP (≤3 HP) and full‑load amps (≤5.5 A).
• Confirm input voltage: 380‑480 VAC, 3‑phase.
• For high overload, choose next size up.
• Select optional keypad for local programming.
• Add communication card if network control needed.
